ROLL FOR CIGAR-MACHINES.

Specification of Letters Patent.

Patented Dec. 17, 1907.

Application filed March 22, 1906. Serial No. 307.526.

To all whom it may concern:

Be it known that we, RroHARD A. BRIGHT and ARTHUR W. DAVIS, both citizens of the United States, residing at Oranston, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in Rolls for Cigar-Machines, of which the folloadng is a specification, reference being had therein to the accompanying drawing.

Our invention relates to that class of rolls which is used for rolling on the wrappers upon cigar bunches already formed, and has for its essential object a roll having the firm but yielding qualities possessed by the human hand. This characteristic is particularly essential in wrapping molded bunches whose binders are particularly fragile. Embraced in the above object is the desideratum of providing a roll which shall possess homogeneity and uninterrupted flexibility and resiliency throughout its length.

To the above ends our invention consists in applying a plurality of concentrically disposed spirally wound layers to a flexible core, each layer being contiguous to or adjacent the next successive layer, in such a manner that the entire roll body, exclusive of the core, shall substantially consist of spirally wound layers. It is preferable for the best effects that alternate layers should be oppositely wound.

We are aware that heretofore a single 'short spiral layer has been soldered to the inner margins of a divided spiral roll shell as a coupling, and that a plurality of spiral sleeves of non-uniform length have been introduced into a limited area of a hollow solid tipped roll as a bushing for a portion of the outer spiral, but these structures and func tions are foreign to this invention.

In the drawings which form a part of these specifications, Figure 1 is a side elevation of our novel roll embodying our invention operatively mounted in the usual yoke or support. Fig. 2, a like elevation of the same partially in central longitudinal section, and partially fragmentary, and Fig. 3, a transverse section of the roll on line x as of Fig. 2.

Like characters of reference indicate like parts throughout the views.

Our roll comprises a metallic core, A,

either straight in contour, or of irregular outline as shown the irregularity of its outline being dependent entirely upon the shape of I the bunch to be operated upon. Upon this core is built up the roll body, B, by a plurality of concentrically positioned spirally wound wire layers, a, a, a a extending substantially the entire length of the roll. The successive layers are preferably wound in opposite directions. In order to give the required taper to the outer end of the roll, the coils of the outer spiral layer, a gradually lessen in diameter towards the roll extremity, and the layers, a, a and a are respectively of sufficiently less length to per mit the tapering of the roll body. The inner together and are inclosed in a sleeve, C. The inner end of the spiral, a is shortened to form an annular recess, a in the rear portion of the roll.

A convenient mounting for the roll comprises the yoke, or frame, D, in which is fixed by a screw, (1, or otherwise a bushing, E, on which loosely turns a, pinion, F, provided with an annular flange, f, adapted to register in the annular recess a of the roll, A, wherein it is held by a binding screw, f, in the collar, C. The inner end of the core is extended longitudinally and rests loosely in the bushing, E. For convenience in mounting, the material of which the core is composed is bent upwardly to form the angular arm, G, whose end is fixed in the yoke or support, D, by a set screw, g.

The spirally wound layers constituting the body of the roll, B, are rotated upon the core, A, through the pinion, F.

Having described our invention what we claim is,

A tobacco roll comprising a core and a plurality of concentrically positioned spirally wound layers upon the core, the successive layers being wound in opposite directions.

In testimony whereof We have affixed our signatures in presence of two witnesses.
